msm: audio: qdsp6v2: Close smd ports upon failure to open.

The smd port acqusition is failing as the port is not
populated from modem . But apr driver was not releasing
the apr handle on failure.
This was resulting in failure for subsequent calls.
With this change, the smd ports will be released upon
encountering failure.
